Walking tree had given us an outstanding training which had helped us to understand and utilize ExtJS framework to the best of its abilities. It was impeccable delivery with high quality people.

We registered a extjs training from WTC and they arranged the same in India and held a classroom course in ExtJS4 for our team. Moreover WTC architectured/designed and developed a part of a system for us, which we have completed. The system is now used by the capital of Norway, Oslo. We get all the help we need on ExtJS, and they have been a great help for us to introduce the use of the MVC structure and object oriented programming using ExtJS. We are very pleased with WTC and will certainly consider to use them also for projects in the future.

5 day training time frame is not sufficient for a developer to learn all features of Sencha what I believe. But I have learned a lot of things. Now I am able to understand the remaining features of sencha. I want the training to be example oriented rather than the normal classroom learning and the trainer should relate the sencha framework to other OOP framework so that It will be easy to learn.

The Sencha ExtJS7.1 course was overall a good interesting training experience. It was the first time for me doing a remote learning course experience but thought it went smoothly. I thought Amita covered through the components and the walkthrough of the example applications thoroughly. Also thought the resource material content is good and is something I want to go back to after the training.
